Forging up, and dual expoing (correct me if I misread you when you said dual exp) into "quick" air is not a viable strategy.
A reliable strategy would be to hold off the initial push and securing your natural. You should be in an economic lead since he sacrificed 7 larvae early on in the game for the attack. From there the game should transfer into a standard ZvP with the protoss being slightly ahead due to a higher probe count.
It should (annhilate|destroy|overwhelm|<etc>) most Protoss players unless they scout...
FTFY
That usage of decimate is as grating to me as it is common. :/ I don't blame you, I'm just shaking my fists at the heavens in impotent rage.
Are you suggesting people should only and exclusively adhere to original meanings and "trve" origins of words?
Knowing where a word came from can certainly help us understand more but let's face it, languages are very alive and change a lot.
